Notes[]
- The
Penalty is triggered regardless of whether Seal Spd's user performs an attack during combat. If foe initiates combat and user cannot counterattack, Seal Spd's Penalty will still trigger. - Seal Spd's user needs to survive the combat for the Penalty to trigger.
- The stat decrease that can be applied by Seal Spd is considered a Penalty.
- Any 【Penalty】 effect on a unit lasts until that unit takes an action. If the unit takes multiple actions in a turn, they will only have Penalties for their first action.
- If the unit also has Grand Strategy, any Penalties will remain active until the start of that unit's next phase.
- If the unit also has
- Any 【Penalty】 effect on a unit lasts until that unit takes an action. If the unit takes multiple actions in a turn, they will only have
- The stat reduction that can be applied during combat by Seal Spd 4 is considered a temporary debuff.
- The "Special cooldown charge -X" effect will stack with the "Special cooldown charge +X" effect.

- If used alongside another source of "Special cooldown charge -X", only the higher of the two charge reductions will apply.
- This means that if a unit has two "Special cooldown charge -1" effects from two different sources, the battle will play out as if only one "Special cooldown charge -1" effect is active.
- Skills such as Tempo Echo and Arcane Þrima will neutralize effects that inflict "Special cooldown charge -X" on its user.
